Oracle java.sql.SQLException:ORA-01002:XATransaction上的提取顺序不正确

在相同的数据上，有时会抛出异常java.sql.SQLException:ORA-01002:fetch，但在大多数尝试中，都可以正常工作

运行在Glassfish 3.1.2.2上的Java应用程序。谁能解释一下，问题出在哪里

@Singleton
@LocalBean
@Startup
@ConcurrencyManagement(ConcurrencyManagementType.BEAN)
public class MarketCodesSingleton {

    @Resource(mappedName="jdbc/sss")
    private DataSource source;

    private volatile static Map<Interval, String> marketCodes;

    @PostConstruct
    @Schedule(minute="*/10", hour="*")
    public void fillMarketCodes() {
        try(Connection conn = source.getConnection()) {
            Map<Interval, String> marketCodesInt = new TreeMap<>();
            DaoFactory.getMarketCodesDao().fillMarketCodes(marketCodesInt, conn);
            marketCodes = Collections.unmodifiableMap(marketCodesInt);
            Logger.getLogger(getClass().getName()).log(Level.FINE, "MarketCodes updated");
        } catch (SQLException e) {
            Logger.getLogger(getClass().getName()).log(Level.SEVERE, "fillMarketCodes exception",e);
            throw new EJBException("fillMarketCodes exception",e);
        }
    }

    public String getMarketCode(Long msisdn) {
        Interval interval = new Interval(msisdn);
        return marketCodes.get(interval);
    }

}

代码不完整，因此我只能猜测：

• 光标已关闭，您试图再次获取
• 您确实选择了更新并提交，然后尝试获取下一行

---

您的连接是否设置为自动提交？跨提交或回滚的获取可能会导致此异常

---

我还注意到，您的SQL并没有像在this和{}中那样被begin/end包围，以确定在遇到异常时是否处理了所有行

修改下面的代码以包含一个计数器i，以获取已处理的行并查找实际的行数

 int i=0;
  try{
 while (rs.next()) {
            Interval interval = new Interval(rs.getLong("from_no"), rs.getLong("to_no"));
            intervals.put(interval, rs.getString("market_code"));
            i=i+1;
        }
}
catch (Exception e)
{
 Logger.getLogger(getClass().getName()).log(Level.FINE, "the total rows processed"+ i);
 Statement stmt = null;
 String query = "select count(1) count_rows                   
               from market_codes";
    stmt = con.createStatement();
    ResultSet rs1 = stmt.executeQuery(query);
    rs1.next();
    String countRows = rs1.getString("count_rows");
    Logger.getLogger(getClass().getName()).log(Level.FINE,"Actual count of rows"+ countRows);
 }

这很奇怪，但通过删除注释@ConcurrencyManagement（ConcurrencyManagementType.BEAN），问题已经解决了

有人能解释一下吗？

正如您在方法fillMarketCodes中看到的，光标没有关闭。在这个方法的rs.next（）上抛出异常，正如您在GET_MARKET_CODES过程中看到的，没有for update语句。我想看看getMarketCodes_SQL的定义。此外，我强烈建议为session.private静态最终字符串getMarketCodes_sql=“CALL SERVICE_PKG.GET_MARKET_CODES（？）”；那是行不通的。执行选择服务\u。。。从dual。只是为了添加，您可以为“rs”添加空检查吗？if（rs！=null）将有助于避免这些异常。请发布您的JDBC连接参数好吗？连接参数已添加到属性设置keepxaontilltxcomplete=“true”，“强制连接池保留物理数据库连接，并在整个事务处理过程中（即，直到分布式事务完成）保持与应用程序的连接。“您的问题可能是由于连接的XA事务上下文在结果集处理过程中发生更改而引起的。我在web上也找到了以下建议：）但我不确定它是否适合Glassfish。我认为，这只适用于Weblogic-
